Looks like it will come out Monday.
iOS 15.3 will be the third major point release of iOS 15 from Apple since it first released the OS to the public in September 2021. Unlike iOS 15.1 and iOS 15.2, though, iOS 15.3 does not pack any significant new features or changes. After
seeding the Release Candidate of the OS to the public a few days ago, the company is now expected to release the final build to the public early next week. If you are looking forward to iOS 15.3, you can find its release time in your time zone below.
iOS 15.3 will patch a major Safari bug in iOS 15 that could potentially
leak your personal data and allow websites to track your browsing history. This is a major low-level bug which is why Apple is rolling out an OS update to fix the issue. The company should release iOS 15.3 and iPadOS 15.3 for all compatible iPhones and iPads on Monday, 24 January at around 10 a.m. PST/1 p.m.
